The objective of this paper is to model thermal burning due to application of a heat source, in the form of a cylindrical disc, through the three distinct layers of human skin, the epidermis, dermis and subcutaneous fat. The temperature of the disc was varied from 50 to 80 degrees Celsius, and was applied for 20 seconds. After the disc was removed, the exposed skin experienced natural convection at ambient air temperature. Metabolic heat generation and blood perfusion in the dermis were taken into consideration. We modeled heat conduction in the skin, tissue damage as a function of time and temperature, and finally, we determined that metabolic heat generation and blood perfusion heat were negligible. The following report introduces our problem, discusses the methods used to generate results and the results obtained, and finally presents our major conclusions and recommendations.
